示例1: Button_Click
private async void Button_Click(object sender, RoutedEventArgs e)
{
//this.txt.Text = DateTime.Now.ToString();
//string x = "";
//HttpClient h = new HttpClient();
//try
//{
// var response = h.GetBufferAsync(new Uri("http://202.202.43.125/"));
// x = await h.GetStringAsync(new Uri("http://202.202.43.125/"));
//}
//catch (Exception xx)
//{
// Debug.WriteLine(xx.Message);
//}
//Debug.WriteLine(x);
//Debug.WriteLine("-=--------------------------------------------------------");
////异步执行并得到结果
//x = await getstring(new Uri("http://202.202.43.125/"));
////异步赋值在执行
//Task<string> rrrrr = getstring(new Uri("http://202.202.43.125/"));
//var c = await rrrrr;
//Debug.WriteLine(x);
